In the early 2000s, a visitor center was built along the Great Ocean Road by the local government, featuring facilities such as parking and restrooms. Additionally, tourists can opt to take a helicopter ride to enjoy aerial views of the Twelve Apostles and their surroundings. These rock formations were shaped by the erosive power of the ocean. Over the past 10 to 20 million years, storms and winds from the Southern Ocean have continuously worn away the relatively soft limestone cliffs, creating numerous caves. These caves gradually enlarged, forming arches that eventually collapsed. The result is the distinctive, towering rock stacks—some reaching up to 45 meters in height—that now stand separated from the mainland.
Some of the stacks have collapsed due to the slow erosion of their bases by waves. On July 3, 2005, one stack crumbled, and another fell on September 25, 2009, leaving only seven standing today. The erosion rate of these limestone formations is approximately 2 centimeters per year. As erosion continues, old "apostles" fall while new ones are gradually formed.
